Guanghao Zhang updated HBASE-23659:
-----------------------------------
Description:
Found this issue when try to fix the flaky unit test TestRegionReplicaSplit.
It may fail as
java.lang.AssertionError: Splitted regions should not be assigned to same
region server.
See
[https://builds.apache.org/job/HBase-Flaky-Tests/job/master/5227/testReport/junit/org.apache.hadoop.hbase.master.assignment/TestRegionReplicaSplit/testRegionReplicaSplitRegionAssignment/].
Now wouldLowerAvailability method only consider the primary regions. The
replica region can't assign to same server with primary region. But can be
assigned to same server with other replica regions.
